Bachmann 108 remotoring

some words by Russ Elliott

With 200g on the drive bogie and a large can motor, Bachmann's 108 has a wild excess of drawbar pull and power. Considering that the same drive arrangement will be used in the forthcoming 4-CEP, Bachmann's approach is to an extent understandable.

This page describes an alternative approach with small motors and sprung bogies.

The overall reduction ratio of the Bachmann drive bogie is approx 13:1. The mesh between worm and gear on the unit as supplied is very poor.

It's a shame that Bachmann felt the need for a mazak casting for the DMBS floor. This is the non-driving end of the DMBS showing the dished cutout necessary to clear the wheel flanges.

The plastic covers representing the prototype engines can be prised off with a screwdriver.
